1. Nsonsonoe bɛn na ɛwɔ mu?

Mpɛn dodow a ɛkɔ soro (HF) – 13.56 mh .z

Dodoɔ:Ɛyɛ tiaa (nsateakwaa kakraa bi kosi anammɔn biako).

Nea eye sen biara ma:Secure, close-akɔ soro.

Wɔde di dwuma wɔ:Kaad a wɔde kɔ hɔ (Office badges), sika a wɔde tua ho ka a wontumi nkasa (apple pay, credit cards), nhomakorabea nhoma ahorow.

Mfaso: .Ɛyɛ adwuma yiye wɔ baabi a ɛbɛn nsu ne dade, ɛboa encryption, saa ara wɔ wiase nyinaa.

Nea enye wɔ ho: .Ɛsɛ sɛ wobɛn scan.

Ultra-mpɔtam a ɛkorɔn (UHF) – 860-960 mh .z

Dodoɔ:ne tenten (anamɔn pii a ɛboro anammɔn 20).

Nea eye sen biara ma:Ntɛmntɛm, a ɛyɛ kɛse a wɔde hwehwɛ nneɛma mu.

Wɔde di dwuma wɔ:Inventory tracking (retail, warehouses), po so hyɛn pallets, nnwinnade a wɔde di akyi.

Mfaso: .Kenkan tag pii prɛko pɛ, tag a ne bo yɛ mmerɛw, tenten.

Nea enye wɔ ho: .Ɛnnyɛ adwuma yiye wɔ baabi a ɛbɛn dade anaa nsu, a ahobammɔ kakraa bi na ɛwɔ mu, mpɛn dodow a wɔde di dwuma no gu ahorow wɔ ɔman biara mu.

2. Emu nea ɛwɔ he na ɛsɛ sɛ wode di dwuma?

Paw HF sɛ:
✔ Wo hia security (te sɛ payments anaasɛ access control).
✔ Worehyɛ nneɛma a ɛbɛn nsu anaa dade ho tagging.
✔ Wopɛ nhyehyɛe a ɛkɔ so wɔ wiase nyinaa.

Nhwɛsoɔ:Kafe shop a wɔde RFID loyalty cards-Adetɔfo bɔ tap na wɔkɔ kɛkɛ.

Paw UHF sɛ:
✔ Ɛsɛ sɛ wo scan fi akyirikyiri.
✔ Woredi nneɛma pii akyi ntɛmntɛm (te sɛ adekoradan).
✔ Wo hia tags a ne bo yɛ mmerɛw a ebetumi aba.

Nhwɛsoɔ:Ntadetɔnbea bi a ɛrehwɛ nneɛma ɔhaha pii prɛko pɛ-UHF yɛ no wɔ sikan kakraa bi mu.

3. Ɔhaw ahorow a ɛtaa ba .

Metal & nsuo: .UHF nsɛnkyerɛnne no yɛ basaa. HF di ho dwuma yiye.

Ɔman Mmara:UHF frequencies gu ahorow (sɛ nhwɛso no, US vs. Europe). HF yɛ adwuma wɔ baabiara.

Tag ntwitwiridii:UHF tumi scan tag pii prɛko pɛ, nanso ɛtɔ mmere bi a ɛtwetwe wɔn ho wɔn ho.

4. Gyinaesi a etwa to .

HF=Ka ho-Kɔ so, ahobammɔ, ahotoso.(akatua, ID nkrataa, tracking ketewa).

UHF=tenten-akwantuo, scanning a ɛwɔ bulk, ɛka a ɛba fam.(adekoradan ahorow, aguadidan ahorow, nneɛma akɛse a wɔde asie).

Woda so ara yɛ obi a onni ahotoso? Bisa:

Ɛsɛ sɛ wo scan kɔ akyirikyiri na ɛyɛ ntɛmntɛm? → UHF.

Wohia ahobammɔ anaa adwuma a ɛbɛn dade/nsu? → HF.

Nhyehyɛe ahorow bi mpo de abien no nyinaa di dwuma, nanso ɛno yɛ nea ɛyɛ den kɛse. Ma ɛnyɛ mmerɛw-Pa nea ɛfata w’ahiade no.
